Evil creatures are monsters featured only during The Eyes of Glouphrie quest. They are spies sent by Glouphrie the Untrusted, first appearing as cute creatures, kept as pets by the gnome population. During the quest, their true form is revealed.
Their combat level is not shown. However, they are attackable and hence they only have 1 life point, they are tied with Chinchompas, carnivorous chinchompas, and the citizens of Miscellania as the monsters with the lowest hitpoints in the game.
